LDAP-imported users have no local passwordHash, and validateUser only checked
the local password, so they could never log in. Now a passwordless user with
an ldapDn is authenticated by binding as their OWN DN with the entered
password against the tenant's active LDAP config (reusing the ldaps TLS-skip
option). Empty passwords are rejected before binding to avoid AD's
unauthenticated-bind bypass. Local-password users are unchanged.
LdapService.verifyUserCredentials added; LdapModule now exports
LdapConfigService; AuthModule imports LdapModule (no circular dep). 8 new
specs (bind success/fail, empty-password guard, login via bind, wrong pw, no
config, no ldapDn, inactive). API 226 green, tsc clean.

Username lookups (login, admin seed, LDAP sync) compared case-sensitively
against a stored value with whatever casing it was created with, so
"Admin" and "admin" were treated as different accounts.
Normalizes at every write and read path: UserService.create/update
lowercase the username before persisting, findByUsername lowercases
the lookup input, AuthService.validateUser lowercases before the login
query, AdminSeedService lowercases the configured admin username, and
the LDAP sync loop lowercases the mapped sAMAccountName before using it
for lookup/create/update -- so AD casing differences don't create
duplicate accounts either.
Added a data migration to lowercase any existing mixed-case usernames.
It relies on the User.username unique constraint to fail loudly if two
existing accounts would collide after normalizing, rather than silently
merging them.
Verified locally: logged in with "ADMIN" (uppercase) against the
existing lowercase "admin" account after rebuilding the API image.

- Add avatarPath String? column to User model (migration: add_user_avatar)
- POST /users/me/avatar: 2MB limit, image/png/jpeg/webp allowlist, writes to user-files/avatars/{userId}.{ext}
- GET /users/me/avatar: streams avatar with Cache-Control: no-store
- AuthService.getMe(): returns isLocalUser + hasAvatar without leaking passwordHash/ldapDn
- AuthController GET /auth/me: now returns enriched profile via getMe()
After a successful password change the old cookie still contained
mustChangePassword=true, causing the middleware to redirect back to
/change-password. Now changePassword issues a fresh session cookie.
